METALJOINT FOR .WlNDOW- GL'ASS.

SPECIFICATION forming part of Letters Patent No. 628,589, dated July 11,1899. 7

Application filed January 17, 1898. Serial No. 666,898. (No model.)

To all whom it may concern:

Be it known that I, HENRY W. RUDOLF, a citizen of the United States,residing at Indi anapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Metal Joints forWindoW-Glass, of which the following is a specification.

This invention relates to improvements in means for uniting the edges ofadjacent pieces of glass of various sizes and colors which are assembledin ornamental patterns in making up what is known as art-glass forwindows and doors. The ordinary practice has been to use a leaden jointI-shaped in cross- 'section, made in strips which are readily out therequired lengths and are easily bent into shape to fit the outlines ofthe pieces of glass which are to be united; but in filling large framesor frames in doors where there is a continual jar the lead is not stiffand strong enough to stand the strain, and the result is the bulging outand the final breaking of the composite pane. Strips of metal likegalvanized sheet-iron have been used,'in which the edges of the striphave been bent to form the flanges. This has remedied the original evil,but has produced another which is almost as serious, for in producingthe double-flanged edges necessary to hold the glass the strip isrendered so stiff that it will not bend freely in any direction and canonly be shaped with the greatest difficulty to fit the contour of theirregular-shaped pieces'of glass used inmaking up the complete designs.

The object of the present invention is to provide a joining-strip whichwill be stiff in direction at right angles to the sides of the the jointto the edges of the glass to be united.

Fig. 3 is a like view of the joining-strip with the glass removed. Fig.4 is a view in side elevation of a part of a strip made in accordancewith my invention, and Fig. 5 is a detail in side elevation of amodified construction.

7 Similar letters of reference indicate like parts throughout theseveral views of the drawings.

A represents the frame within which the glass is mounted.

B are the pieces of glass, which will vary in size and other physicalcharacteristics with the design or pattern which it is intended toproduce, except that the edges will all be approximately of uniformthickness in the same design.

0 represents my improved joining-strip, which comprises a web of thinsheet-iron 0, although copper or other material having the requisitequalities of strength and rigidity under a strain edgewise of the stripand flexibility sidewise might be used in place of iron,

and c are laterally-projected flanges of lead,

The metal for the web is cut in strips of suitable width and is placedwith the lead in a melting-pot and is drawn from thence through a die,together with the molten lead. The

die gives the lead the shape required for the flanges. The strip isready touse as soon as it is sulficiently cooled.

The web of iron stiffens the complete strip in a direction edgewise ofsaid web; but when the latter is made out of thin sheets it will bendfreely sidewise., and the lead flanges will serve to hold the shapewhich may be given to the web in bending it sidewise. The flanges may bevaried in shape in cross-section, and the finished strips can be made invarious sizes to suit the job on which it is to be used.

Should it be desired to use a web which is not tinned, a series ofperforations 0 as shown in the modification in Fig. 5, may be formed inthe web, whereby the flanges will be made to adhere thereto.

margins only of said web, and projecting laterally therefrom,substantially as described and for the purposes specified In witnesswhereof I have hereunto set my :5 hand and seal at Indianapolis,Indiana, this 7th day of January, A. D. 1898.
